USER MANUAL

PORTABLE uP-BASED

pH METER

MODEL: SM102

Smart pH Meter

OPERATION:

• The meter is supplied complete with a

9V battery. Slide off the battery compart-

ment cover on the back of the meter

and install the battery while paying at-

tention to its polarity.

• Always remove the electrode protective

cap before taking any measurement. If

the electrode has been left dry, soak

the tip (bottom 2.5 cm) in rinse solution

(M10000B) for a few minutes to reacti-

vate it.

• Connect the pH

electrode and the

temperature probe

to the sockets on

the meter’s top.

The temperature

probe can be used

independently to

take temperature

measurements, or

it can be used in

conjunction with

the pH electrode to utilize the meter’s

ATC capability.

• Turn the instrument on by pressing the

ON/OFF key.

• Before taking any mea-

surements, make sure

that the meter has al-

ready been calibrated.

• Immerse the tip (2.5 cm)

of the pH electrode and

the temperature probe

into the sample and stir

gently.

• Take the pH reading when the hour-

glass symbol stops blinking.

• To display the mea-

sured temperature,

press and hold the

°C key.

When the key is released, the display

will return to the pH reading.

• The HOLD function is activated by

keeping pressed the HOLD key.

The measured value is frozen on

the display and the “HOLD” tag

lights up.

• After measurements, switch the

meter off and store the electrode

with a few drops of storage solu-

tion in the protective cap.

• Error message on display:

CALIBRATION PROCEDURE:

A) Preparation:

Reference solutions:

1. pH 7.01 (MA 9007)

2. pH 4.01 (MA 9004) for measuring

in the acid range (pH lower than 7)

or pH 10.01 (MA 9010) for measur-

ing in the alkaline range (pH higher

than 7).

Use two beakers for each reference so-

lution. One beaker for rinsing the

electrode, the other for calibration. This

way contamination between solutions

during calibration is minimized.

B) Procedure:

• Remove the electrode

protective cap and rinse

the tip with some

pH7.01 solution, then

immerse the electrode

and the temperature

probe into a pH7.01

buffer solution.

• Press the CAL key

to enter the Cali-

bration mode. The

display flashes

“pH 7.01” and the

hourglass lights up.

• Blinking full scale value: reading is

over range;

• “Eb”: battery low voltage indication;

• “Ec”: wrong buffer solution;

• “Clr”: the calibration data have been

lost and recalibration is needed.

WEIGHT 220 g (with battery)

Note: Pressing the CAL key again will

change the required buffer value,

making possible a single point cali-

bration at pH 4.01 or pH 10.01.

• Wait till the hourglass symbol on the

display turns off and the “pH” tag stops

blinking, then

press the CFM key

to confirm the off-

set calibration. “pH

4.01” will flash on

the LCD.

• Rinse the pH electrode

and the temperature

probe in the first pH4.01

beaker, then immerse

them into the second

pH4.01 beaker.

• Follow the same procedure if using the

pH10.01 solution; select the correct

buffer by pressing the CAL key.

• Wait till the hourglass symbol on the

LCD turns off, then press the CFM key

to confirm the slope calibration.

Notes:

• To exit the calibration mode, turn the

meter off by pressing the ON/OFF key.

• To perform a single point calibration

(offset) at pH7.01, press the ON/OFF

key when the second buffer is asked.

• After battery replacement, the meter dis-

plays the “Clr” message and

recalibration is needed.

BATTERY REPLACEMENT:

When the battery becomes so weak that

no reliable measurement can be guaran-

teed, the meter will display “Eb” for a while

and then turns off.

It is recommended to replace immediately

the battery.

Battery replacement must only take place

in a non-hazardous area using a 9V alka-

line battery.

Turn the meter off, slide

off the battery compart-

ment cover at the rear of

the meter and replace

the 9V battery with a new

one.

Make sure the battery

contacts are tight and

secure, seat the battery

in its compartment and

insert back the cover.
